Problems solved by technology

However, the above studies did not involve the water absorption characteristics of brown rice under natural soil conditions. Therefore, further research is still needed to optimize the process based on the germination law of brown rice under natural conditions.

Embodiment Construction

[0016] (1) Pre-germination treatment of brown rice: remove impurities, broken grains, no germs, mildewed grains and heterochromatic grains of the raw brown rice, then sterilize it with ultraviolet light for 10-15 minutes, determine the moisture content of the raw material to be 12%, and weigh 10kg for use. .

[0017] (2) Brown rice moisture adjustment: Put the brown rice raw material processed in step (1) at room temperature. In this example, the weight of the brown rice raw material is 10 kg, the initial moisture content is 12%, and the initial moisture quality of the material is 1.2 kg. Through real-time monitoring of the flow rate of the water adding nozzle and the moisture content of the brown rice material, before the moisture content of the material is 18%, the hourly increase rate of the moisture content is selected to be an average of 1.0% / h, by the formula: water quality = (target moisture content × initial moisture content of the material Mass-initial material mass) / (1-...

Abstract

The invention belongs to the technical field of further processing of grain, and in particular relates to a process for optimizing the production of germinated brown rice. The process is characterized in that the engineering method is used to simulate according to the natural germinating process of rice in a soil environment condition, the high germination rate and high gamma-aminobutyric acid content in germinated brown rice are the targets, and on that basis, the optimization process parameter combination meeting the demands on water absorption, temperature, ventilation and other conditions for germination of brown rice are obtained. Compared with the traditional brown rice germination process, the process, provided by the invention, has the advantages that the link of soaking is avoided, so that the natural germination rules of brown rice are met, no sewage is produced, the loss on dissolution of nutritional substances of the brown rice in soaking is avoided, and the energy consumption for drying of the germinated brown rice due to excessive water sucking in the soaking link can also be decreased. With the adoption of the process for optimizing, the germination rate of brown rice can be increased by 5 to 7%, and the gamma-aminobutyric acid content in germinated brown rice can be increased by about 2.4 times.

Description

Technical field [0001] The invention relates to a new process for the production of germinated brown rice, mainly related to the humidification method of brown rice before germination, aiming to reduce the cracking rate of brown rice during germination, increase the germination rate of brown rice and the content of nutrient γ-aminobutyric acid, reduce energy consumption and avoid sewage Emissions belong to the field of grain deep processing technology. Background technique [0002] my country is the world's largest rice production and consumption country. With the improvement of people's living standards and changes in consumption concepts, people have higher and higher requirements for the nutritional value and health functions of rice. About 60% of the nutrient elements in rice are accumulated in the bran layer and germ which account for about 10% of the rice quality. Therefore, the traditional rice processing method causes a great waste of nutrients. Although the nutritional ...
